There are about 36818 clinical studies being (or have been) conducted in China. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
This study is a randomized, double-blind phase Ⅳ clinical trial of quadrivalent influenza vaccine (Split Virion), inactivated manufactured by Sinovac Biotech Co., Ltd.The purpose of this study is to evaluate the lot-to-lot consistency, immunogenicity and safety of quadrivalent influenza vaccine (Split Virion), inactivated in health subjects aged 9-59 years old.
Neoadjuvant therapy is feasible in stage Ⅱ-Ⅲ melanoma, Carrelizumab combined with apatinib and temozolomide has synergistic antitumor effects and may improve pathological response.
The primary aim of this prospective, multicentre study is to determine whether the involved node can be marked using black carbon dye and successfully identified at the time of surgery. The secondary aims are to determine the concordance between the tattooed node and sentinel node, migration of black dye into other nodes, and false-negative rate of tattooed node (in patients undergoing ALND after NACT).
the aim of this study was to evaluate the accuracy of the various virtual articulator mounting procedures.
The purpose of this study was to investigate and compare the variation in mandibular relation recorded by the gothic arch methods and the K7 method using cone beam computed tomography (CBCT)
This is an ongoing Phase 2, open-label, single-center, non-randomized study of sintilimab (one anti-PD-1 antibody same as nivolumab approved in China) plus bevacizumab administered in a low dosage schedule in adult (≥ 18 years) participants with a clinical relapse or circulating tumor DNA (ctDNA)-level relapse of Oligodendroglioma(WHO III). This study has three non-comparative study groups. Cohort 1 and Cohort 2 will receive the same study drug sintilimab 200mg and bevacizumab 3mg/kg every 3 weeks. Cohort 3 will take only standard treatment. A stringent three-step non-randomized process will be used to assign participants to one of the study groups. Neither participants nor doctors but the researcher can choose which group participants are in. No one knows if one study group is better or worse than the other. 80 total participants are expected to participate in this study (30 participants in Cohort 1 and Cohort 2). Grouping process: After enrollment, under the standard of care, participants will receive regular tumor in situ fluid (fluid within the surgical cavity, TISF) sampling for ctDNA analysis and recceive regular MRI. The researcher will study the TISF ctDNA and imaging dynamics to determine whether the tumor reaches to ctDNA-level (Cohort 1) or clinical relapse (Cohort 2). At the first step, all timely identified as ctDNA-level relapse tumors will be assigned into the Cohort 1 and receive the study drug immediately, those failed to be timely identified will be assigned into the Cohort 2 and receive the study drug after the clinical relapse. At the second step, once Cohort 1 or Cohort 2 reaches the target number, the new participants will be all assigned into the other Cohort. In the third step, if no CTDNA-level or clinical relapse was observed within 60 months after surgery, patients were assigned to Cohort 3 and further analyzed for prognostic biomarkers compared with Cohort 1 and Cohort 2.
Little is known about the evolution of genetic and epigenetic changes that occur in the progression of glioma. We inferred the evolution trajectories of matched pairs of primary tumors and progression tumor in situ fluid (TISF) based on deep whole-genome-sequencing data (ctDNA). A monocentric, Gene grouping controlled trial design was used to select patients. and to compare gene evolution of different subtypes of glioma under therapy. To predict the molecular reaction of bevacizumab treatment, clarify the mechanism of drug resistance of bevacizumab treatment.
This study is the first prospective randomized study assessing the patient-reported outcomes and safety outcomes between preoperative and postmastectomy radiotherapy in locally advanced breast cancer patients with immediate reconstruction of deep inferior epigastric perforator(DIEP) flap. Radiotherapy before mastectomy and autologous free-flap breast reconstruction can avoid adverse radiation effects on healthy donor tissues and delays to adjuvant radiotherapy. We aimed to explore the feasibility of preoperative radiotherapy followed by DIEP flap reconstruction in patients with breast cancer requiring mastectomy.

To compare down sizing strategy versus annular sizing strategy technique (control group) in Type 0 bicuspid aortic stenosis (AS) patients undergoing transcatheter aortic valve replacement (TAVR) with self-expanding valves (SEVs): a randomized superiority trial
